This invention relates to tenter-link or clip.

and has for one offits 4 objects the provisionof simple and effective} means for releasably retairi ing the swinging ews: the clip out otengage ment with the fixed jaw during the-returnmove ment of the clip for anotherj engagement with the Y traveling web; of cloth.

Anotherobject of this invention is the provision of a construction thejaw of which may be opened and released from. open position from the face of the clip whereby a pluralityof superimposed clips may be independently operated without interference witheach other;

Another object of theinvention is the passion of a construction for holdingfand releasing the swinging jaw 'as desired, and which' willoper ate in conjunction withf'aj plurality of superim posed swinging jaw structures independently of each other. f 3

With these and other objects in view, the 'in-.

.ventionconsists of certain novelfeatures of construction, as will be more fully described and par:

ticularly. pointed out in the'appended clai ns,

' In the accompanying drawingzj Fig.1 is a side elevation of a tenter link equipped with this invention. v

Fig. "2 is a central sectional"viewthereof with the swinging jaws held in open position."

Fig. 3 is aface view; and e i Fig. 4"is aperspective view wi h'partsbrcken away showing the latch engaging the "control memberfor tion. a

Fig. 5 is a perspective view of the swinging jaw with the latch mounted thereon. In the use of tenter chains it is frequently desirable to provide a construction whereby the swinging jaw is maintained out of engagement with the fixed jaw during the return of the link from its position of gripping the cloth. In some maintainingthe jaw in raised positentering machines there are used as tenter links constructions the known form of means for holding the jaws open during return movement cani not be used as they are mounted on the top and require releasing from the top of the link; and

in order that the swinging jaw may be held open in a link having superimposed clips, I have provided a latch which is mounted on the swinging jaw and protrudes from the face thereof and which may be released by engagement with the arm of the latch protruding from the face as 'well as opened by engagement with the face, and

thus? each jaw. operates 'entirely 'indee pendently of the otherand any desired number theffollowing is'a' detailed description of 'the present embodiment. of this invention illustrating the preferred means'by which these advanta geous results maybe accomplished. g

With reference to the drawing, l q designates the base of thetenter link which isprovided with an ear ll at one endthereof and'a pair or ears [2 at the otherend thered space'd apart a dis; tance'to receive the ear: I l=-of another link-[and be attached thereto by the usual pivot pin(not r hown)" f 'nncc h l n s l ich n rmation. K The superstructure on the body of this tenterchain consists" of asupport l3 having an overhanglngportion l4 and a shelf portion I 5 between the body and the overhanging portion I l. The base portion provides onejfixed jaw; 6 while the shelf portion provides another fixed jaw I] andc qpera mswit t se e i s there r with the jaw l8 pivoted as at to the lower portionofthe shelf l5 and the jaw ISflpivoted as. at 2 I: to the overhanging arm I 4 of thejsupport l 3, j

pivotally mounted the swinging jaws [Band 19,

J The swinging jawsare each hung to move'by gravity towards their fixed jaws and are controlled in their swinging movement by the feeler members22, 23engagingthe roller 24 provided on the reeirwardlyektending arms 25 of. each of the swinging jaws .Thesepontrol feeler memf bers rest upon the cloth in the usual *manner holding the jaw out of engagement therewith until the edge of the cloth passes beyond the edge of the feeler members and the slot 26 after which the jaw drops quickly into engagement with the fabric and retains it in the desiredposition.

In order that the swinging jaws l8 and [9 may be maintained in open engagement, as illustrated in Fig. 2, I have provided latches?! and 28 on V the swinging jaws l8 and I9 pivoted between the ears 29 and 30 provided on each swinging jaw with each latch of a sufficient length to engage the control member and prevent its falling by gravity when in raised position, as illustrated in' Fig. 2. I The latches 21 or 28 fall by gravity into struction which maybe utilized upon any number of superimposed clips on the chain link and be readily operable from the face thereof.

' The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of, the appended claims. i

I claim: I 7

1. A tenter clip having'a fixed jaw, a cooperating pivotally mounted swinging jaw, a latch pivotally mounted on the swinging jaw, between the pivot of said jaw and the gripping edgeIthereof means including a feeler member cooperating with the latch to hold the swinging-jaw in open position, said latch provided with an arm protruding from the faceof the swinging jaw to be engaged for tripping the .latch for closing the swinging jaw. r

2. A tenter clip' having a fixed jaw, '21. cooperating pivotally mounted gravity actuated swinging jaw, a gravity actuated latch pivotally mounted on the swinging jaw, between the pivot of said jaw and the gripping edge thereof means comprising a feeler member cooperating with the latch to hold the swinging jaw in open position, said latch provided with an arm protruding from the face of the swinging jaw and at an angle to the plane of the same when in closed position'to be engaged for tripping the latch for closing the swinging jaw. 1

3. A tenter clip having a fixed'jaw, a cooperating pivotally mounted swinging jaw, a feeler member for controlling the closing movement of said swinging jaw, a latch pivotally mounted on said swinging jaw between the pivot of said jaw and the gripping edge thereof and engageable with said feeler member for. maintaining the swinging jaw in open'position.

Further; this construction does not interfere with a por 4. A tenter clip having a fixed jaw, a cooperating pivotally mounted swinging jaw, a feeler member for controlling the closing movement of said swinging jaw, a latch pivotally mounted on said swinging jaw between the pivot of said jaw and the gripping edge thereof and engageable with said feeler member for maintaining the swinging jaw in open position, said latch having an arm, protruding forwardly fromthe face of the swinging jaw to be engaged for tripping the latch to permit closing of the swinging jaw.

" -5. A tenter clip having a fixed jaw, a cooperating pivotally mounted gravity actuated swing- "ingjaw, a feeler member for controlling the closing movement of said swinging jaw, a gravity actuated'latch pivotally mounted on said swinging jaw between the pivot of said jaw and the gripping edge thereof and engageable with said feeler member for maintaining the swinging jaw in open position.

6. A tenter clip having a fixed jaw, a cooperatingpivotally mounted-gravity actuated movable jaw, afeeler member for controlling the closing movement of said movable jaw, a gravity actuated latch pivotally mounted onsaid movable jaw between the pivot of said jaw and the gripping edge thereof and engageable with said feeler member for maintaining the movable jaw. in open position, said latchfhaving. an arm protruding beyond the face of the movable jaw to beengaged for tripping the latch to permit closing of themovable jaw. H 7. A tenter link having superimposed fixed and swinging jaws, a latch mounted on each swinging jaw adjacent to the gripping edge thereof, means cooperating with each latch to hold the swingingjaw in open position, andan arm on each latch protruding from the face of the swinging jaw'to be engaged to trip the latch for closing the swinging jaw, means positioned on saidswinging jaw adjacent to the gripping edgethereof to be engaged for opening said jaw.
